The HTTP 401 error when generating a dataframe in Superset could be related to authentication issues. Here are a few things to check:

1. Session Management: Ensure that session cookies are properly managed and not expiring unexpectedly. Superset uses Flask-Login for session management, and the session lifetime can be configured with PERMANENT_SESSION_LIFETIME ^[1].

2. Token Expiration: If you're using OAuth2 for data source access, verify that the access tokens are valid and not expired. Superset attempts to refresh tokens if a refresh token is available, but if both are invalid, it will result in a 401 error ^[2].

3. Slack Integration: Check the SLACK_API_TOKEN configuration to ensure it's correctly set and not causing authentication issues ^[3].

4. Kubernetes Configuration: Ensure that your Kubernetes deployment is correctly handling environment variables and secrets related to authentication.

Review these areas to identify potential misconfigurations or expired tokens that might be causing the issue.
